Unequal Pupils in Unconvicted Prisoners

13q32.1 as a candidate region for physiological anisocoria

“…) is an asymmetry of pupil diameter in the absence of any pathology [1,2]. Its incidence has been reported for a number of populations [1][2][3][4][5][6]: the reported frequency will clearly depend on the criterion difference in pupil diameter that is adopted, but values of the order of 20% have been given for a threshold difference of 0.4-0.6 mm [4]. Physiological anisocoria is known to depend substantially on the illumination conditions used for the measurements [2,4,7,8]; and the size of the asymmetry for a given person may vary from one test occasion to another [9].…”
